Project template for rp2040-hal

This template is intended as a starting point for developing your own firmware based on the rp2040-hal.

It includes all of the knurling-rs tooling as showcased in https://github.com/knurling-rs/app-template (defmt, defmt-rtt, panic-probe, flip-link) to make development as easy as possible.

probe-run is configured as the default runner, so you can start your program as easy as

DEFMT_LOG=trace cargo run --release

Requirements

• The standard Rust tooling (cargo, rustup) which you can install from https://rustup.rs/

• Toolchain support for the cortex-m0+ processors in the rp2040 (thumbv6m-none-eabi)

• flip-link - this allows you to detect stack-overflows on the first core, which is the only supported target for now.

• probe-run. Upstream support for RP2040 was added with version 0.3.1.

• A CMSIS-DAP probe. (JLink probes sort of work but are very unstable. Other probes won't work at all)

  You can use a second Pico as a CMSIS-DAP debug probe by installing the following firmware on it: https://github.com/majbthrd/DapperMime/releases/download/20210225/raspberry_pi_pico-DapperMime.uf2

  More details on supported debug probes can be found in debug_probes.md
